Specification of Letters Patent.

Patented June 1,1915.

Application led July 13, 1914. Serial No. 850,666.

,a resident of the city of Hamilton, in the county of lVentwor-th, in the Province of Ontario, Canada, and JACOB Cnms'rorrnin ADAM, a citizen of the United States, and a resident of the town of Trenton, in .the county of Hastings, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Trolley-lVheels, of which the following is the specification.

Our invention relates to improvements in trolley wheels, and the object of the invention is to devise a simple and effective trolley wheel of the ball bearing type in which the ball bearings can be inserted into the wheel and removed therefrom with a minimum of trouble.

A further object is to construct a trolley wheel` in which the ball bearings are interchangeable.

A still further object isto construct a trolley wheel having the minimum of friction and which can be effectively lubricated without splashing the lubricating oil over the tcp of the car.

Another object is to devise a-trolley wheel in which any of the parts can be removed with greater facility than in the trolley wheels at present in use` ur invention consists of the parts constructed and arranged as hereinafter more particularly described and illustrated in the accompanying drawings in which t- Figure 1 represents a cross sectional view of a trolley wheel constructed according to our invention. Fig. 2 isa side view thereof partly in section.

Like characters of reference indicate correspondingr partsin the different views.

1 and 2 are the portions of a divided trolley pole harp.

3 is the aXle extending through the harp portions andsecured thereto by the pins t.

5, 5 are independent collars secured to the axle 3 by the key 6.

'Z is a trolley wheel portion having the hollow interior or center 8 provided with circumferential grooves 9 extending to the sides of the trolley wheel.

10, 10 are ball races on the collars 5.

11, 11 and 1Q, 12 are the portions of the divided annular ball race portions respectively secured together by the rivetsv18, and

having the ball races 14 on the inner surface thereof, said ball races registering with the ball races on the collars.

15, 15 are balls inserted between the ball races.

16, 16 are the inwardly extending Shanks on the collars 5, said inwardly extending Shanks carrying the pins 17.

18 is a key inserted between the ball race portions 13 and 14 and the wall of the groove ,9 for securing the ball race portions to the .trolley wheel portion and compelling the same to turn therewith.

19, l9iare plates counter-sunk into the sides of the trolley wheel portion and suitably secured thereto by the Yscrews 20.

Vaseline or other suitable lubricant is adapted to be inserted into the hollow center 8 of the trolley wheel portion. Thus when the trolley wheel portion 7 and the ball races ll, 12, are connected the vaseline will properly lubricate the balls and will prevent any friction in the ball races. :Further the vaseline or other suitable lubricant revolving to a certain extent with the trolley wheel portion will be stirred or agitated by the pins 17. Thus an effectively lubricated wheel will be produced and one which will be capable of giving the maximum of service. Further when it is desired. to removepthe ball bearings it is only necessary to remove the plates 19 and the key G when the ball bearings can be removed as a whole. The ball bearings are interchangeable and can beinserted with equal facility into either side of the trolley wheel portion; also as the lubricant is heavy and as the wearing parts are totally ineased there is no danger of the lubricant being thrown about as so frequently occurs in the self-oiling wheels at present in use.

`What we claim as our invention and desire to secure by Letters Patent isz- 1. In combination in a trolley wheel, an axle Awith bearing elements keyed thereto, lubricant agitating means carried by said elements, of a rotatable member having recesses, bearing elements located in some of said recesses, plates located in other of said recesses and antifriction members located between the first mentioned and last mentioned bearing elements.

2. ln combination in a trolley wheel, an axle with bearing elements keyed thereto, radial pins carried by said bearing elements,

lil() a rotatable member having recesses, bearing `worth, in the Province of Ontario, Canada, elements located 1n some of said recesses, this 8rd day of June, 1914.

plates located in other of: said lrecesses and HENRY CARL ADAM antifrietion members located etween the w r 1 iirst mentioned and last mentioned bearing JACOB (JHRSFOPHER ADAM elements. Witnesses In testimony whereof, We have signed at J. E. M. FETHERSTONHAUGH, j

the city of Hamiton, in the county of Went- F. J. GAVIN.
